Analysis Lethal dose Ficus carica L. cv. Sabz irradiated with different doses of gamma-ray.
The regression equation obtained was Y = 0.9791x - 22.158, where Y represents the survival percentage, and x represents the irradiation dose in Gy. The coefficient of determination (R2) was 0.86, indicating a strong correlation between radiation dose and survival percentage.

Effects of different gamma irradiation doses on leaf traits in Ficus carica L. cv. Sabz.
Data analysis revealed that higher doses, ranging from 50 to 90 Gy, led to a reduction in leaf area for fig hardwood cuttings compared to those exposed to lower doses of gamma irradiation (10, 20, 30, and 40 Gy). Our results indicate that the smallest leaf area was observed in response to higher doses of gamma radiation, particularly at 80 Gy (2623 mm2), 90 Gy (1652 mm2), and other lower doses (5306 mm2). Moreover, gamma ray treatments such as 50, 60, and 70 Gy had a moderate impact on the leaf area of fig cuttings.

Cluster analysis of the studied traits in different gamma treatments in Ficus carica L. cv. Sabz.
This approach showed that three distinct groups. The initial group encompassed the control treatment, as well as the 10, 20, and 30 Gy treatments. Notably, the control and low-dose treatments displayed a minimum negative effect in terms of leaf, shoot, and root characteristics compared to the other treatments. Furthermore, within this group, both the 10 Gy and control treatments outperformed the 20 Gy and 30 Gy treatments.
